However the vast majority of writings on this sub-3mewhat different, narrower terms. Either because the possi-oseful interference with a fertility trend is not contemplated ie assumption that the economic cost of such interference is usual approach is merely to analyze the economic conse-jothetical or observed differences in fertility, bypassing the v those differences are to be explained in the first place. Thus, irting from a given initial situation, in the fashion of the by-[y of Coale and Hoover (1), alternative courses of fertility over ecified as affecting the same initial population, and the conse-ous economic indicators may be worked out by plugging the jlation trends into an appropriate model describing the work-omy in question.

Once the net economic benefits of a / are worked out (as a rule tacitly assuming that the reduction 10 economic costs), the level of those benefits may be related :s of any proposed scheme that is capable of engineering the on specified in the calculation.
